-Be it known that I, GEORGE H. PEAL, a

Coffee Brewers, of which the following is a .p specification.

This invention relates to a coffee brewer. l v lAn ob'ect of the invention is to provide a simple, c eap and efficient device suitable for containing a quantity of ground coffee and o adapted to be lsuspended within a fpotof boiling water, the device being per orated and bein the water may reach the coffee.

A further object is to so construct the i' device that it is expansible tosuitablyl accommodate any expansion of the contained coffee.. Y

` A further object is to provide a suspension.

cord or vwire lconnected with the device in a manner to maintain the device assembled.y

A further and more detailed object is to .construct the device yof two separatel formed and.` substantially identical cylindrical. sectionstelescoped one within the other,4 eing perforated and be.

said sections'both ing movable relative to each other to brin the perforations of the two sections into an out of register' at will and to permit of convenient increase in the interior area of the device upon occasion, the two sections being held 'together by'asuitable cord or wire in such mannerv as not to interfere with the p mentioned functions and said cord or wire having an extendinfr art by which the device may be suspen e within a pot of boiling)water.

ther objects and aims of the invention,

A more or less specific than those referred to l v constructed to permit ofad'ustment of t e size of the openings thru w ich:

invention, being partly broken away and shown in transverse section for the better disclosure of details.

Figure 2 is a plan View of the blank einevo ployed for forming one ofthe sections of the brewer.

Figure 3 is a diagrammatic view illustrating the manner in which .the blank is wrapped around a suitable mandrel in the process of forming one of the sections.

Figure 4 is a similar view illustrating the manner in which a ortion ofthe blank is folded down over t e end of the mandrel to complete the section, and v Figure 5 is an enlarged fragmentary view illustrating the manner in which the perforations of the two sections of the brewer are obstructed as when the brewer is not in use. Referring to 'the drawings for describing in detail the structure therein illustrated the reference character L indicates one of the sections of the brewer while the reference character G illustrates the other section. These sections may be formed of any ap ro'- priate material but in practice it has en found that ver thin sheet aluminum is an ideal'material or the purpose. Each of the sections is formed from a perforated sheet as seen in Fig. 2, the sheet being first wrapped about a suitable die or mandrel H at a tposition so that a portion as 1 -of'the cylin er formed by the sheet projects beyond-the end of the mandrel as seen in Fig. 3. lThe projecting portion 1 is then folded and creaseddown over the end of the mandrel as seen in Fi 4. Ordinarily no. other means is require for holdinor the section thus produced in its cylindrical form.

' To produce the brewer two of these sections are employed and the are connected to ether by being telescope one within the oter. The inner section is of course first filled with the coffee as 2 before introduced r into the outer section.

After the sections are assembled then a cord or Wire 3 is passed axially thru the brewer, its opposite ends *be-ing brought around and being twisted together at one side of the brewer. A separatev cord' or wire 4 may be connected with the wire 3 for carrying an advertisement, or finger grip tag 5, or said cord or wire 4 ma be made as an integral extension of the cor or wire 3 as illustrated.' p

The two sections employed for .forming a single brewer maybe formed upon mansingle size mandrel. ln being assembled the inner section will compress slightly` while the outer section will expand slightly. 'lhe manner in which the sect-ions are constructed also facilitate this result, it being noted in this connection that the lapping parts as 6 and 7 ot' the sheet forming the section are not rigidly connected together in any way but are left free to move slightly relative to each other so that they thereby permit limited variation in the diameter of the section at any time after the section is formed.

It is noted further that the manner in which the closed ends or heads, as 8, of the sections are formed permits said heads to bow readily into either concaved or convexed shape. Preferably when the sections are originally formed these heads are slightly convexed `Substantially as seen in Fig. 1. When the cord or wire 3 is threaded thru the device and is bent around the sections as indicated it provides shoulder portions as 9 which 0bstruct free separating movement of the sections. Nevertheless since4 these shoulders occur centrally of the heads it' follows that the two sections may be moved apart within appreciable limits while the heads are bent by the shoulders 9 from their original convexed shape to a concaved shape. Within these limits of movement the perforations 10 of one section may move into and out of register with the perforations 11 of the other section so that thus a user may readilycause any desired amount of free passage thru the sections to and from the coffee. This adaptability of the sections to moved apart within the limits also avoids the possibility that expansion of the contained coee while brewing might cause such crowding as to make the device inoperative.

By rotating the sections relative to each other also the user may bring the apertures 10 of one section into and out of. register with the apertures of the other section for determining the amount of free passage thru the sections to and from the coee, and this provision, in addition to the provision to the same end by moving the sections longitudinally ot each other, enables the user to accomplish the object without tedious manipulation.

Due to the slight, but nevertheless sufcient inherent resiliency of the material of which the sectionsare formed, the compression or enlargement of one or both of said sections will of course operate, whenl l the sections are telescoped together, to urge return of the sections to their normal size, and will thereby create a close rictional engagement `of the sections one with the other. which is a feature of considerable .value not only in that it serves to hold the members assembled and in any position to which they are manually moved but also in that it prevents the presence of any excessive air passages between the opposing walls and thereby renders the operation of bringing the perforations into andout of register more precise and ellicent.

ll'hile the drawings herewith Show the sheet of material employed to be perforated only in that part which forms theV side walls of the sections yet it will be understood that if desired the perforations may be formed also in the portions of the sheet conf stituting the end wall or head of the section.

It is intended that brewers constructed in accordance with this invention may be manufactured and sold, with their coffee contents, as articles of manufactureA for individual use and that having been once used they are to be discarded and not again used. The material employed in their manufacture is extremely cheap and is of such nature that having been once used it could not readily be relled and used again.

lVhile the device is intended primarily for use in the brewing of coffee nevertheless it will be understood that it may be as readily employed or numerous other materials as may suggest themselves according to the nature and structure of the device.

As many changes could be made in this construction without departing from the scope of the invention as deined in the following claims, it is intended that all matter contained in the above description or 'shown in the accompanying drawings, shall be interpreted as illustrative only and not in a limiting sense.

In some instances the member 3, when made of wire or the like, may be suiliciently still so that it will serve its intended functions Without being extended entirely thru the brewer. In this case the portions of the wire extending along the ends and side of the brewer will operate, by their stiffness, to cause the ends of the wire, centrally of the heads of the sections to indent into or puncture thru the material of said heads and will maintain these ends in engagement with the heads for holding the sections assembled in the same manner as already described.
